SAFETY RAZOR.

Application. filed. February 2, 1925. Serial No. 6,498.

This invention relates to cutting implements and in particular to sharp-edged in struments designed and used for shaving the face or head, and in which devices are employed for preventing the cutting of the skin and in which a detachable blade may be also adjusted both forwardly and rear- ,wardly as well as in angular relation. After having been adjusted the blade may be rigidly held in a detachable relation.

By my invention a handy, serviceable safety-razor is provided which is simple in construction, inexpensive to manufacture and eflicient and reliable as well as durable in practical use. v

ith these objects, and other objects and purposes which will. be hereinafter described, in view, the invention consists in the construction, arrangement, combination and operation of parts set forth below.

In the drawings, illustrative of one embodiment of the invention, which accompany and form a part of this specification Figure 1 represents a plan view of an article constructed according to my invention; Figure 2 is a view in section of my blade holding mechanism;

Figure 3 is a rear view of my safety razor; and 1 Figures 4, 5, 6, 7 8 and 9 are elevations of blades adapted to be used with my blade holder.

The body of my safety razor comprises generally speaking the following elements tary in form. This remark also applies to the construction of other features of this invention. I

The upper plate 1 is preferably'made to carry a forwardly projecting portion which I call a hood 30 or pocket, the same ordinarily being made with side walls, said hood exthereof. The numeral 1 denotes an upper plate or properly a blade carrying plate, while nu-' For clearness ofillustration I have shown 1 tending forwardly from the upper thickened portion 31 of plate 1 and being preferably made in one piece with the said upper thickened portion. The. latter is also preferably. made in one piece with the lower thickened portion 82 in such a way that the upper thickened part 81 extends above, and the lower thickened portion 32extends below the plate 1 at a right angle thereto.

The plate 1 has two longitudinal guides 'formed bythe side edges of the same beinglapped over toward each other to prevent lateral movement of the blade, which plate has an open central portion 35 which extends rearwardly to the thickened portions 31 and 82 and at its front edge the said plate is equipped with the ordinary guard fingers 5 having a dip and being curved at the ends thereof.

A bore 6 extends through the parts 8132' which latter have a recess 33 at the end of the bore adjacent to the rear of the blade, in which bore a screw 20 works, a flange 21 of which is enclosed in said recess. The opposite end of the swivelled screw 20 is threaded. and is provided with a screw-head 3 the base ofwhich slightly overlaps the entrance of the bore 6, thus making the base of the screw-head function as an upper collar or flange co-acting with the flange 21.

The thickened part 3132 is bored diagonally at 7 which threaded bore enters the part 31 near the upper edge and corner The said bore is slanted downwardly and inwardly to accommodate a plain screw 8 whichscrew after leaving the bore continues its downwardly and'inwardly slanting direction in order to press on the flat surface of the blade at 9.

The lower forward side portions of the, plate 1 are preferably reinforced as at 3 1 so as tohold screws 10 which are constructed and arranged to pass at an angle through threaded orifices in the said plate and to extend through perforations 11 inthe said guides and also to engage the retaining devices at the side edges of said blades.

My razor is designed to provide for the adjustment of the blade by a longitudinal movement of the same on the body of the holder, to prevent by the use of retaining means and detents any undue forward movement thereof, to rigidly maintain the blade in the forward adjusted position and to keepthe blade from any lateral movement thereof, and to hold the same rigidly against the razor body during the operation of shaving.

On account of the handle of the razor being adapted to be held at various angles to the body thereof it is necessary to provide positive means to prevent any lateral displacement of the blade at the time the strain or stress, occasioned by the said angular position of the handle, occurs.

I accomplish these results by the employment of the following mechanism, namely:--

I preferably use blades 12 made with a thickened rear part 13 and also provided with lateral abutments or retaining devices as for example recesses 14-, shoulders 15 and 17, rectangular slots 16 or curved slots 18, although, if desired, in some cases the blades may be constructed with straight side edges as shown in Figure 9.

I prefer to use blades 12 not only made with a thickened rear part 13 but also provided with a threaded orifice 19 at its rear edge in which a screw 20 may work, the annular flange 21 of which may rest in the recess 33.

It is obvious that if the bore 6 and the screw body 20 between the flange 21 and the detachable screw head 3 were not threaded said screw body 20 would turn around in the bore 6 without any forward movement; whereas the lower or outer part of the screw outward of the flange 21 being threaded it will engage the blade orifice 19, and by thus turning the screw body the blade may be advanced in position or moved rearwardly in the guides 4 according to the adjustment desired. In some cases however it may be.

preferable that the blade shall be moved to such a position that the detents, as screws 10, shall rest against the inner abutments formed by the retaining devices 14:, 15, 16, 17 and 18 thereby preventing any farther or undue forward movement of the blade.

If now the screw 8 is manipulated said screw will by its contact with the blade at 9 force the blade downwardly and rigidly against the outer edges of the plate 1 and prevent any upward movement of the said blade.

It can be readily understood that if the orifice 19 were to be closed the screw 20 couldbe made to work back and forth in the bore 6 in which case the screw would merely press the blade in a forward direction, and

that where such a movement alone is desired it would be possible to accomplish this by threading the flange 21 using a widened threaded recess 33, or as an equivalent means by simply closing up orifice 19 or omitting orifice 19, omitting also the flange 21 and recess 33 and by threading bore 6 and the whole length of the screw 20.

The plate 2 is preferably made with an upturned semi-circular rim 22 and a series of engaging devices 23 on the lower face of said plate, said engaging devices in the present instance consisting of corrugations. laterally adjustable handle-support 2 1 is preferably pivoted at 25 to the plate 2 and carries an overhanging lip 26 engaging the inner and outer edge of-the rim 22, the said support also bearing a screw 27 to co-act with the engaging means to hold the support within its plane of operation at any angular position desired as regards the body of my razor and the cutting edge of the blade.

A handle 28 may be secured to the support r an upper collar or flange coacting with flange 21. Said screw 20 upon leaving bore 6 is made square to engage the square hole of screw head 3 and may be split and bent over outwardly at the sides of said base as at 20, thus securing screw head 3 firmly to the screw 20.

I wish it to be understood that I do not desire to be limited to the particular use or the exact details of construction shown and described, for obvious modifications will occur to persons skilled in the art.
